Roof & Gutter Deicing Controller

The GC-1 heating cable controller has been designed and manufactured for the sole intended use of controlling heating cables in residential and commercial roof and gutter deicing applications. The GC-1 uses microcontroller technology to reduce energy consumption by energizing the heating cable only when the appropriate temperature and moisture conditions occur.

The GC-1 controller includes the MSG-1 sensor, used to detect moisture on roofs and in gutters. Roof moisture detection is made with the unique sensor wire design; the sensing grid on the bottom of the MSG 1 detects gutter moisture. The MSG-1 housing sits directly in the gutter and the sensor wire is secured to the roof. The combination roof and gutter detection system provides quick detection of potentially damaging roof and gutter icing conditions. If the temperature is below 3°C (38°F) and the MSG-1 sensor detects moisture, the controller will apply power to the heating cable. The cable remains energized until 3 hours (hold time) after the sensor is dry.

The MSG-1 sensor operates on low voltage provided by the GC-1 control unit and includes mounting hardware and 30' of wire for connection back to the GC-1. The GC-1 automatically detects and sets-up for supply voltages between 120VAC and 277VAC; no dipswitches or jumpers are required. The GC-1 has a LED indicator to display when cables are energized. It is also possible to connect a remote control to the GC-1 (model GCR-1, sold separately). The remote allows the deicing hold time to be custom set, and provides for a manual start/stop.
